Subject: [PATCH] usb: ehci-omap: drop unused ehci_read() function

From: Arnd Bergmann <arnd@...db.de>

After moving the omap1 platform into generalized multiplatform
support on ARM, the kernel test robot points out a W=1 warning that
now shows up in more configurations:

drivers/usb/host/ehci-omap.c:64:19: warning: unused function 'ehci_read'

The function was last used 9 years ago and can just be removed.

Fixes: 87425ad36330 ("USB: ehci-omap: Remove PHY reset handling code")
Reported-by: kernel test robot <lkp@...el.com>
Signed-off-by: Arnd Bergmann <arnd@...db.de>
